SWITCH FOR ELECTRIC LINES.

Application flied December 29, 1921. Serial No. 525,769.

To all whom it may concern Be it known that I, CARI. GoLnBnRo, a citizen of the Czechoslovak Republic, residing at Langegasse No. 357, Haida, Czecho- 5. slovak Republic, have invented certain new and useful Improvements in Switches for Electric Lines, of which the following is a specification.

My invention relates to a switch. It is a 10 well known fact that difficulties are often encountered as to the manner of placing the switch within an electrolier of finer make,

especially in standard lamps made of glass,

porcelain or the like, the switch being often 15 so inaccessible that in using them one may run the risk of upsetting the lamp so that it seems indeed troublesome to cut the lamp in or out. Therefore plug contacts are generally 20 used, which however are likewise undesirable because when cutting out the lamps the electric connection is completely broken.

My invention overcomes all these drawbacks in that the electric wiring which 2 leads to the electrolier is provided with a switch mechanism. Thus an electrolier may be made without any regard to the placing of the switch therein, the latter moreover being quite accessible.

The switch connecting the electric line preferably is made as a sliding contact.

In the drawing, which shows a preferred embodiment of my invention,

Fig. 1 shows a part of an electric wiring, 35 the switch being shown in longitudinal section,

Fig. 2 is a transverse section and Fig. 3 a side elevation of the switch. A switch (2')) is inserted in an electric line 4 (a) the latter being secured at one end to the electrolier and at the other end to the I feeder or .to a plug contact. 7

The switch (6) which may bemade of porcelain or the like contains a longitudinal partition (7 and is provided with the terminals (d d) and (g g) respectively for connecting the electric line. The terminals (9 g) are permanently electric-ally connected by means of a metal strip (9"), whereas the terminals (d d) are insulated from each other, but may be electrically connected by means of a sliding pin From the latter projects outside of the switch cover (6) a handle made of any insulating material, its shaft (lc) being adapted tomove in a slot or recess (2') of said cover (1)).

Of course, I do not intend to limit my invention to the embodiment shown and described because, instead of the sliding pin for making the electric connection, also other means can be used for that purpose.

I claim:

In combination with an electric wiring,'a switch comprising a casing of insulating material and having openings for admitting the wires thereto and made of two parts, onepart containing a groove and the other being provided with a web engaging saidv groove and forming two separate compartments in said casing, electrically connected terminals in one of said compartments, separate terminals in the other compartment, metal sleeves connected with the said last named terminals, a pin slidingly mounted within one of said sleeves and adapted to engage the other sleeve so as to electrically connect the said separate terminals, and means projecting outside of said casing for operating said pin.

In testimony whereof I affix my signature in presence of two witnesses.
